To all lwho-melf may concern.' i Be it kno-wn that I, JOHN XV. KoHLHErr, a citizen of the United States, anda resident offthe'lcity of Chicago, in the county of Cook and State of Illinois, have invented certain nevv and useful Improvements in Scraping- `lVIachines; and I do hereby declare that the- 'following is a full, clear, and exactdescription of the same, 'reference being had to the accompanying drawings, and tothe numerals'ofreferencc marked. thereon, which forni a art o-f'this specification.

v i his invention relates to that class of hog scraping 'machines in which the carcass is4 simultaneously supported, rotated, scraped n and advanced through the machine by co-V voperative rolls assisted in their operation Vby adj ustably mounted beater mechanisms. By utilizing the supporting and conveying means as a scraping mechanism, the dehairingoperation'is greatly Ifacilitated and a much less time is required to dehair the hog y than where separate mechanisms for conveying. and scraping are provided.`

Thisinvention has for its object mechanisms for receiving a hog or carcass floated thereon and advancing and elevating the/A same out of the water in the tank while subjecting the saine to the action of a number of adjustable beating mechanisms, alternate Aones of which aredriven in the same direction and adjacent'ones oppositely, and inv which the elevating and conveying mechani m act efficiently to dehair the carcass du rinits progress lthrough the machine.

It lis an object of this invention to construct a lmachine wherein a pluralitylof similarly constructed and symmetrically disposed ro-lls are mounted in inclined position in a tank, eachpair of rolls adapted to re-4k ceive-a.carcass and handle the same independently to convey and scrape the' carcass while continually rotating the same and subjecting the carcass to the action of a number of beaters disposed above the rolls. It is also an object of this invention to f prov/idea machine of double capacity, that isto'say the same tank is used to contain the hot water in which the carcasses are..1m-' mersed prior to their introduction on Vto thescraping mechanisms, there' being duplicate sets of Vscraping mechanisms, each'one adapted to handle a carcass independently of the other. Y

I Itis also an object of this invention to Specification of Letters latent.

Patented Apr. 25, 1916. 1914.v serial 110.826,22.

construct mechanisms for supporting and conveying a carcass longitudinally while continually rotating thel same, and with beaters adjustably mounted to swing longitudinally of the carcass to dehair and polish the same.

It isA also an object of this invention to construct a device wherein a plurality of adjustable Vbeater mechanisms are mounted above inclined supporting and scrapin'grolls driven at diiierent speeds, in a manner such that adjacent beaters above saidY rolls operate in opposite directions upon the carcass illustrated in the drawings and hereinafterA more fully described.

In the drawings: Figure l is a side elevation of a device embodying the principles of luy-invention. Fig. 2 is an end elevation of the discharge end thereof. Fig. 3 is a top plan view of the device with the top wal`\ removed. Fig. 4 is a longitudinal, centralx verticall section taken through a device with parts inelevation. Fig. 5 is a transverse vertical section taken on line 5-5 ofFig. 4, with parts omitted. Fig. 6 is ai etail showing in plan a pair of cooperative scraping and conveying rollers.

As shown in the drawings, the machine embraces a substantially rectangular tank-1,

which, at the entrance end, communicates with a scalding tank 2, from whichvthe carcasses are received to be operated. yupon.

' Mounted in said tank 1, and inclining up- Wardly from the entrance end toward the discharge endare shafts 3 and 4, respectively, and secured upon said shafts to rotate therewith are scraping and conveying rolls- 5 and 6, respectively. As shown, there are two 'of each of said shafts 3 and 4, and likewise two of each of said rollers 5 and 6.

The duplication of the respective rollers 5 and 6, is to double the capacity of the machine and embody the mechanisms in a single tank, the operation and construction of each of the parts of theJnechanisms being exactly similar. Said shafts 3- and 4, are mounted in such a manner within the tank 1, that the roller 5, is below and to one side of the roller 6, and, as shown, is of larger diameter than said roller G. Secured upon the surface of each of the rollers are a plurality of scraping members 7, arranged thereon in the form of a continuous helix, so that upon contacting with a carcass they not only serve to scrape the same, but also to advan'ce the cai;- cass longitudinally of the roller. Each of the. rollers (i, is provided with se'apers arranged in straight lines thereon, so' that with rotation of said latter rollers a carcass which is supported mainly upon the roller in a longitudinal position, is scraped transversely by the Scrapers on the roller 6.

A perforated sheet metal casing member is bent around beneath each of the respective rolls 5 and (3, to conform to the curvatllre thereof, as indicated by the reference numeral 9. and is bent upwardly centrally of the machine between the. two rolls 5, eX- tending upwardly therebetween to afford 'a partition l0, the sides of which slope toward said rolls 5. .lournaled within said tank 1. transversely thereof. and .at points in a line substantially parallel said shafts 3 and l.

are a series of shafts, each denoted b v the.

reference. numeral il, and haviugseeured on its end on the exterior ofthe casing l` a sprocket wheel 12. Ay maindrlvmg shaft. l-.

. is jouri'ialrd across the discharge end of the machine. and secured thereon is a sprocket Wheel 14, over which ls tralned a chain 15, said chain also bcmg engaged upon the respective sprocket wheels 12, inthe manner shown in Fig. l. so that adjacent shafts 11, arc caused to rotate in opposite directions. Two pairs of swinging arms, denoted respectively by the reference numerals 1G :and 17.

. are mounted upon each of said shafts ll, and

Support at their ends beater or scraper shafts 1H. journaled therein with' onel shaft disposed over each of the lrespective rolls 5 and (i. `Qprockct wheels 19,'are` keyed upon said shaft ll, near each end thereof adjacent the arms ltr. and likewise sprocket wheels 90, are secured upon the shafts 1S, and a chain 2l, is trained over said sprocket wheels to transmit an independent drive to each of said shafts 1S, from said shaft 1l.

A plurality of beaters, each consisting of four' resilient arms Q2. are secured upon each ofsaid shafts 13, and at their ends are tippedv with lsteel scrapers.- lt is readily apparent from the construction described that each of the shafts 1S. is permitted an independent pivotal movement about they respective supporting and driving shaft 11,

and the gears 19 and 20, and chain 21, which transmit the drive from the shaft 11,.to said shaft 18. permit adjustment of said latter shaft without interfering with the drive.

Rigidly secured upon the upper or forward ends of the shafts 3, are sprocket wheels 23, and likewise sprocket wheels 24, are secured upon the upper forward ends of said shafts 4, on thc exterioisof thel casing at theV discharge end. Short stud shafts Q5, are journaled in bearings 26, on each side of the casing, and are each provided at one end with a large and small sprocket wheel, denoted respectively by the reference numerals .17 and Q8, of which the large sprocket wheel 27, isconnected to the sprocket '2-1, by means of a chain 30, and the small sprocket 2S, is connected to the sprocket 23, by means of a chain 29. Af bearing bracket 31. similar to the bearing bracket 2G, is secured upon each side of the casing directly below said bearing bracket 2G, and is likewise provided with a short stud shaft on one end of which is a bevel pillion i2, which meshes with a pinion 33', rigidly secured upon the main driving shaft 13, to receive power therefrom; (ln the other cud of the `stub shaft supporting the pinion 32. is a sprocket wheel 34, and a chain 35. is trained over said sprocket wheel aml a similar sprocket wheel 36, upon theA end of the shaft 25, in said bearing bracket 16. whereby the drive from the main shaft 155. is transmitted through said bevel pinions and sprocket wheels and chains to the respective roller shafts 3 and l.

()f course, the respective sprocket wheels 2T and 2S,.are in a vertical plane. whereas the pinions 23 and "2l, are inclined in a plane. whichjds at "right angles tothe inclined shaftsand 4. but. due to the iexibility of the chains which connect the respective sprocket wheels one .to another. il is possible to transnrit the power. although the connected sprocket wheels are indifferent planes. driving pullev 37. is provided on thev end if the power shaft li. to receive power from any suitable source, such as a motor.
